摘　　要：除反映物理稳定性的输电阻塞外,电力市场还受到一次能源、环保排放、技术支撑及多方博弈等因素的制约。这些因素都会影响竞争水平和市场效率,建议将这些影响统称为广义阻塞。监管的目的是为了避免市场力被滥用,并保障社会福利。但监管不当也会降低市场效率,甚至危及市场稳定性或社会稳定性,故也是一种广义阻塞。市场参与者通过广义阻塞来影响(损害或提高)市场效率的能力称为市场力,而广义市场力则反映对社会福利的影响能力。从分类、评估指标、研究方法及控制等方面评述广义阻塞、市场力和广义市场力问题。为全面的研究提出框架,以便应用实验经济学方法,综合分析各种广义阻塞影响市场力的机理。Besides the transmission congestion reflecting the physical stability of a power system,power market is also constrained by factors like primary energy,emissions,technical support and multi-game.These factors affecting both competition level and efficiency of a power market can be called by ageneric term as generalized congestions.The purpose of regulation is to avoid the abuse of market power and reduce the risk in social welfare.However,inappropriate regulation may also degrade the efficiency of a market;even endanger the market and social stability.So regulation is also a kind of generalized congestions.The capability of market participants to influence（increase or decrease）market efficiency through taking the advantage of generalized congestions can be called as market power,while generalized market power reflects the capability to influence social welfare.Generalized congestions,market power and generalized market power are analyzed in aspects such as classification,evaluation indexes,control measures and research methods.A framework is proposed for the mechanism study of generalized congestions,market power and generalized market power.With this framework,experimental economics can be implemented,and comprehensive analysis can be taken to study the mechanism for generalized congestions to influence the market power.
